Randy Udall on Climate Change

June 5, 2012
UN Climate talks in Copenhagen and Cancun set a 2-degree target for limiting climate change. Some experts including NASA's Jim Hanson think that's still too high, but it's a number that has been widely accepted. On this episode of NRG with MG, energy expert Randy Udall is back with KDNK's Marilyn Gleason from Bonfire Coffee in Carbondale to discuss the science behind the 2-degree cap on global warming.
